DescriptionSpecificationsFrequently Asked Questions
Uni-ball Signo UM-151 gel ink pens, also known as Signo DX, are known for their smooth writing and exceptional ink quality. And, to everyone's delight, there is a sea of colors and tip sizes to choose from. Find the perfect pen for any task, whether it's writing meticulous notes, marking your calendar, or decorating your scrapbook with colorful captions.

Everything about this pen, from its solid construction to its carefully-formulated ink, ensures a wonderful writing experience. The sturdy tip does not bend or break, even with heavy-handed use. The pigment-based ink flows smoothly and is waterproof, fade-resistant, and feather-resistant. Much of that is due to special viscous properties of the ink. The ink is viscous while in the barrel, but as it passes through the pen tip during writing, the viscosity drops. This results in smooth ink flow. Immediately after it hits the paper, the ink returns to its viscous state, which prevents feathering. You are left with beautiful clean lines that you can enjoy for a long time!

I compared a green G-tech C4 .4mm with the green Uni-Ball signo 151 .38 mm. I used a cheap index card and wrote with both pens then poured two separate drops of sparkling water and let it stand for a couple of hours. After the hours past the G-Tech c4 washed out (you could still make out what was written but barley) and the lines of the index card faded away. The signo writing was STILL THERE as if I just wrote it. One thing that is different between the two is the color. One the g-tech c4 the green ink is more saturated and the signo has hints of yellow in its hue. Dont get me wrong the signo ink is very pleasant and its waterPROOF ability makes it a great pen. If waterproof ink is not important then the c4 and 151 are both nice.

These are my favorite pens. I love writing extra tiny and these are the only ones that do the job for me. Others are too inky and these are perfect.

I'm a huge fan of the tiny point and the color. The ink flows very well and writing with it is a pleasure. The design is also simple and quite pleasant.

These will most likely be my new go to pens for everything.
